I Create the Big BOSS Behind the Scenes

"Lord Yalishan! It's not good! The Mongolian army has reached the outside of the city!" "Great Khan! Not good! The Qin Empire is approaching!" "Your Majesty! It's not good! Those undead people are here again!" ———— When the Great Qin, the Great Han, the Great Ming, the Great Tang, the Great Song, the Great Qing, the Great Yuan... Were in the same world... ———— The earth has been running for nearly five billion years, and endless garbage has been produced in the system. As the new owner of the earth, Zhang Xiaoyu has to clean up this garbage. It's too slow to clean up by myself, so we can only ask the players to help.
